Question

What is a Micrometer used for?

Answer 1

Hint: To define the Micrometer according to the area of application and its nature. To mention the various fields in which this tool is applicable and relied upon. Describe the structure and how the micrometer tool is assembled which will help in determining the precision and accuracy of the tool.

Complete step by step answer:
 A micrometer is an instrument that's used for creating exact linear measurements of dimensions like diameter, thickness, and lengths of solid bodies. It’s made of a C-shaped frame with a movable jaw which is operated by an integral screw.
Micrometers convert small distances into large rotations of the screw that may be read from a scale. A micrometer is relied upon when a clear-cut measurement is required. A micrometer can measure the depth, length, and thickness of any object that matches in between its anvil and spindle. It’s generally utilized in technology and machining applications. The list of uses of the micrometer is as given below
Machines with moving parts – Parts that move in an exceedingly in and out of every other like the piston have to remain in a steady line, otherwise, the slightest little bit of sway can cause faults.
Bearings and pipe fittings need proper measurements for optimal functioning.
Micrometers are a favored tool for the measurement of the thickness of things like metals.
Portability, ease of use, and measuring consistency are some of the key advantages of micrometer

Note:
For a micrometer, the screw located within the barrel is taken into account at the center of the micrometer. The accuracy of the thread from within the screw defines the accuracy of the measurement. The thread of the screw is just the ridges felt when touching a screw. The thread is that the helical structure that's moving up the screw which converts torque to linear force.
